CVE-2025-48541

Local privilege escalation via external profile identifier

Published Sep 4, 2025 · Updated Feb 26, 2026

Improper input validation in Android 13 through 16 allows local users to remove biometric unlock from another user profile. FaceSettings.onCreate trusts an externally supplied android.intent.extra.USER_ID value, so a caller from one profile can target another profile's face settings. A low-privileged local caller needs no user interaction, and exploitation disables the targeted profile's biometric unlock.
